CP 6632 is a handheld accurate calibrator for process signals (150 ppm reading accuracy) that measures or generates process current and voltage. Robust and easy-to-use, this instrument has been designed to make maintenance operations easier on sensors and transmitters using process signals such as 4-20 mA or 0-10 V.
The instrument is adapted to the various process installations due to scaling function and specific ranges. It can simulate ramps, steps and fixed values to control process transmitters, panel meters and recorders.
Temperature coefficients are low: 15 ppm /°C in voltage and 20 ppm/°C in current. The high accuracy of 150 ppm makes CP 6632 an ideal standard for onsite use even in demanding environmental conditions.
CP 6632 is delivered with 4 alkaline AA batteries in standard. The optional battery charger used a rechargeable battery.

Further features
| Scaling in measurement and simulation modes | This function allows sensors to be corrected after a calibration. Scaling is performed using up to 10 segments, in order to fit with the real calibrated value. |
| HART compatibility | Equipped with a non-disturbing digital transmission resistance, it is possible to measure the current output of any transmitter using HART protocol. |
| Statistical functions | Continuous display of average, minimum and maximum value of the signal under monitoring, as well as number of measurements. |
| Simple and cyclical ramp generation | Ramps can be generated by setting low and high dwell, rising and falling times, stabilization and delay times (1 to 3,600 s). Delay time enables a single user to launch the ramp and go to the control panel. |
| Steps simulation | This mode allows predefined values to be sent with programmable amplitude and frequency. |
| Square root | In current measurement and simulation, this function allows taking into account a quadratic signal coming from transmitter of type ΔP. |
